AUDIOPHILE INTEGRATED AMPLIFIER

Dear customer,Thank you for purchasing a Micromega product. This unit provides ease of use and sonics of the highest quality. Please pay close attention to this instruction manual, and read it fully before attempting to operate. It is designed to ensure that you maximise your pleasure of listening to MyAMP.

CheckingCheck that the carton has no damage. Should you have any doubt about its condition, please do not hesitate to contact your dealer. Opening the box, you should find:• C5 power chord• Remote control handset and one CR2025 Lithium battery (do not forget to

remove the plastic protection for your battery).

Mains voltageMyAMP mains power supply is designed to match the following mains voltage and frequency range : 85-150 Vac / 47-63 Hz, or 180 - 265 Vac / 47-63 Hz. Please check that the voltage indicated on the label located above the ac inlet of your unit, matches your home mains voltage. If not, DO NOT PLUG THE AC MAINS CHORD and get in contact with your dealer. In any case, you will not be able to change MyAMP ac mains voltage by yourself.

Interconnect cablesExcept for the mains power chord, MyAMP is supplied without interconnect cables. To get the most out of your unit, we strongly recommend to use good quality inter-connect cables. MyCABLE offers a range of cables matching perfectly with MyAMP quality requirements. We offer short cables, especially designed for My products as well as Loudspeakers cables designed as the perfect complement of MySPEAKER, the best match loudspeakers to MyAMP.


Wiring

MyAMP has 3 line level analog inputs AN1, AN2 and AN3, one USB 24/96

digital input, and two 24/192 SPDIF coaxial and optical inputs. Beside, MyAMP is

equipped with an aptX® Bluetooth module with outstanding sonic performance.

A pairing switch located on the back panel of the unit allows connecting many

different Bluetooth devices giving each one the possibility ot listening to its own

music on MyAMP.

A SUB output gives you the possibility to add an active subwoofer to your system

if needed. The RECORD ouput sends the analog signal content, just before the

volume control, to and external device such as a recorder or a processor.

MyAMP has also a trigger input to control the Standby / On status of the unit by a

5 to 12V DC trigger voltage. On the same connector you can also send, from an

external system, RC5 remote control codes to access directly all MyAMP functions.

The TRIG/IR IN connector wiring diagram as well as the list of remote control codes

is available on our web site under MyAMP/Support.

On MyAMP front panel your will find a 3.5mm headphone socket. When inserting

a headphone jack the loudspeakers are muted and the headphone volume control

setup becomes independent from the loudspeakers one.


MyAMP power amplifiers operate in class AB, thus needing a heatsink. MyAMP is cooled by forced convection, thanks to an extremely quiet fan and a proprietary extrusion profile designed by Micromega. This profile can be seen on each side of the unit. Despite the fact that MyAMp is fully protected against abnormal heatsink temperature rise, it is strongly recommended to allow 10cm minimal free space on the left and right sides of the unit. This way, the air flow from left to right will not suffer any constraints.

You can install MyAMP in a closet as long as it is equipped with air input and output with sufficient surface and a good ventilation to avoid any air temperature rise that would trigger MyAMP over temperature protection system.

The following diagram gives you an example how to connect different units to MyAMP.

Powering up

Once having connected all your system units to MyAMP, you can now plug in the ac line chord supplied with the unit.

MyAMP is now in “Standby” mode indicated by a red led located below the MyAMP logo on the bottom left hand side of the unit front panel.

MyAMP meets the latest environment energy regulations and requires less than 500mW in “Standby” mode, making unnecessary the use of a power switch, removing the electrical stress at each turn on and off will lengthen the life of com-ponents.

The stanby red led is also used as remote control reception indicator.


Front panel description

On the left hand bottom side of the front panel, you will find the MyAMP logo with

the red “Standby” led located just below.

In the middle of the unit, from bottom to top you will find the 3.5mm headphone

jack, with the IR received just above and a vertical row of 10 leds. The first led, just

avove the IR receiver is the red “Mute” led. Then 8 white leds indicate the volume

level and finally at the top of the row another red led indicate clipping when blin-

king and maximum level when always on.

On the right side of the front panel, from bottom to top, there are 3 control tact

switches “SEL”, “VOL-” and “VOL+”. Three white leds indicating analog input selec-

tion “AN1”, “AN2” and “AN3” are located above the tact switches and then three

other white ones used to indicate digital input selection “USB”, “OPTO” and “COAX”.

Finally at the top of the right side of the front panel a Bluetooth logo is framed on

the left by a red led and on the right side by a blue one. Please read the Bluetooth

paragraph for more details about MyAMP bluetooth input.

Operation

MyAMP can be controlled by the three tact switches located at the bottom right hand side of the front panel or by the remote control handset supplied with the unit.

A short pressure on the unit “SEL” key or “Standby” button of the remote control handset takes MyAMP out of “Standby” mode.

A 15 seconds waiting period has been implemented to allow the complete stabilization of the internal circuitry as well as perfect silent operation. During this period, where the red “Standby” led is blinking slowly, no operation is allowed.

Once out of standby, the mute led goes off and the unit selects AN1 or the latest selected source before going into standby with the volume set to a minimal level. A long pressure (more that 2 seconds) on the “SEL” key or a short press on the “Standby” button of the remote control handset, places MyAMP in Standby mode again.

You can select the proper volume level by pressing on the VOL- and VOL+ keys on the unit on the remote control handset. A long press on each volume key gives you the possibility to increase or decrease rapidly the volume. When increasing rapidly the ramp will stop at a predefined level, loud enough but not too loud to damage any speaker. Once that level is reached, if you want to increase the volume you will have to do it step by step.

To select another source than the selected one, press on the “SEL” key of the unit until the desired source is reached or use the direct access keys of the remote control handset. Each time a source is changed, MyAMP goes into mute for 500ms to avoid any switching noise.

When selecting a digital source, MyAMP will unmute when a correct digital stream is re-ceived. Otherwise , the unit will stay muted with the red mute led on, and no change in the previous volume setup possible to avoid unexpected level changes.

Bluetooth input

MyAMP is equipped with an aptX® Bluetooth module.


The Bluetooth input is indicated on MyAMP front panel by a Bluetooth logo framed by two leds, a red one on the left side and a blue one on the right.

When selecting the Bluetooth input for the first time, MyAMP is in pairing mode , the red and blue leds will flash alternatively. You should now be able to see MyAMP in the list of Bluetooth units on your Bluetooth device. Connect your device to MyAMP following your device connection procedure. Once connected, MyAMP front panel indicator will change status: the red led will switch off and the blue led will flash every 2 seconds. From your Bluetooth device you can start sending music to MyAMP. As soon as MyAMP will receive a valid data stream the front panel blue led will stop blinking and will stay on as long as MyAMP receives music.

You can connect up to 8 different Bluetooth units to MyAMP, actually, allowing every member of the family to listen to its own music.

To connect a new device to MyAMP you must enter pairing mode first. To access pairing mode, a microswitch is located on the back panel of the unit indicated by BT/PAIR. Using a toothpick or any similar object , press at least 2 seconds on the pairing switch. On the front panel, the red and blue leds will flash alternatively indicating that you have entered pairing mode. You should be able now to see MyAMP in the list of Bluetooth devices on your Bluetooth unit. Connect your device to MyAMP following your device connection procedure. Once connected, MyAMP front panel indicator will change status, the red led will switch off and the blue led will flash every 2 seconds.

Once 8 devices have already been paired to MyAMP, if you try to pair an additional device the first one that was paird to MyAMP will be erased and replaced by the new one. You can always decide to erase the list of devices that were connected to MyAMP Bluetooth module. To do so, you need to press the pairing switch for more that 10 seconds and the Red led will blink 5 times on the row indicating that the memory was erased.

To guarantee MyAMP musical reproduction integrity, the Bluetooth module is only powered when selected, avoiding any interaction between analog and digital signals. You will need to connect your Bluetooth device to MyAMP again when you select the Bluetooth input.


Below you will find a shortlist of MyAMP Bluetooth status indications.
